Composer程序包创作：如何指定程序包是模块？

Question

我正在编写Drupal 8模块，对作曲家来说是新手。我想知道如何将软件包指定为模块，以便可以将其安装在正确的存储库中。

现在我的模块的composer.json看起来像这样：

{
  "name": "company/module_name",
  "description": "Module Description",
  "type": "drupal-module",
  "keywords": ["the", "keywords"],
  "time": "2019-04-18",
  "authors": [
    {
      "name": "Me",
      "email": "me@example.com",
      "role": "Developer"
    }
  ],
  "repositories": [
    {
      "packagist.org": false
    },
    {
      "type": "composer",
      "url": "https://git.company.com/project.git"
    }
  ],
  "autoload": {
    "psr-4": {
      "Project\\": "src"
    }
  },
  "require": {
    "php": ">=7.0.0",
    "mpdf/mpdf": "dev-master"
  },
  "minimum-stability": "stable"
}

我怀疑我缺少composer/installers软件包，但是任何建议都会受到欢迎。
